[0082] In order to enable a more clear understanding of the above-mentioned purposes, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0083] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present disclosure, but the present disclosure can also be implemented in other manners different from those described herein; obviously, the embodiments described in the specification are only a part of the embodiments of the present disclosure, and not all the embodiments.

[0084] The hydrogen peroxide generating device and the application thereof will be described in detail below through specific embodiments:

[0085] Referring to FIGS. 1 to 3, Figures 1 to 5 , and Figures 13 to 19 Some embodiments of the present disclosure provide a hydrogen peroxide generating device 10, which comprises a shell 11, a liquid inlet 17 and a liquid outlet 18 arranged on the shell 11, the liquid inlet 17 is used to be connected with a water supply component, the shell 11 is internally provided with a cathode sheet 12 and an anode sheet 13 for electrolyzing water to generate a hydrogen peroxide solution, and the liquid outlet 18 is used to discharge the generated hydrogen peroxide solution.

[0086] That is to say, the water from the water supply component enters the inside of the shell 11 through the liquid inlet 17, and is electrolyzed into hydrogen peroxide by the electrolysis effect of the cathode sheet 12 and the anode sheet 13 inside the shell 11, and the electrolysis generated hydrogen peroxide solution is discharged from the shell 11 through the liquid outlet 18. The hydrogen peroxide solution has good cleaning, odor removal, disinfection, sterilization and other functions, so when the hydrogen peroxide generating device 10 is applied to household appliances (such as laundry washing equipment, laundry treatment equipment, dishwashers, refrigerators, air conditioners, dehumidifiers, etc.), it can play a good role in cleaning, odor removal, disinfection, sterilization and the like.

[0087] Specifically, when the hydrogen peroxide generating device 10 is applied to washing equipment (such as laundry washing equipment such as washing machines, dishwashers, etc.), it can realize cleaning of the washing object under the condition of reducing or even not using detergent, enhance the washing effect, reduce the amount of detergent, realize low-carbon environmental protection, and make the user not need to frequently add detergent to the washing cavity; when the hydrogen peroxide generating device 10 is applied to some other household appliances (such as laundry treatment equipment such as clothes dryers, care cabinets, refrigerators, air conditioners, dehumidifiers, etc.), it can effectively remove odor and ensure the cleanliness of the air, thereby improving the user's experience.

[0088] In specific implementation, the hydrogen peroxide generator 10 is installed in a household appliance. The inlet 17 and outlet 18 of the hydrogen peroxide generator 10 can be connected to the liquid pipeline already present in the household appliance, or to a liquid pipeline additionally installed in the household appliance for connecting the hydrogen peroxide generator 10. The inlet 17 of the hydrogen peroxide generator 10 can also be at least partially immersed in the washing water, thereby realizing the generation of hydrogen peroxide solution by electrolyzing water using the hydrogen peroxide generator 10. This achieves the purpose of using the hydrogen peroxide solution to enhance the cleaning ability of household appliances such as washing equipment, as well as the deodorizing, disinfecting, sterilizing, and purifying effects on household appliances such as dryers, care cabinets, refrigerators, air conditioners, and humidifiers.

[0089] In some embodiments, refer to Figures 1 to 5 As shown, the housing 11 includes a first housing portion 111 and a second housing portion 113 connected to each other. An electrolysis chamber is formed between the first housing portion 111 and the second housing portion 113. A housing frame 114 is disposed in the electrolysis chamber. The cathode plate 12 is disposed between the first housing portion 111 and the housing frame 114, and the cathode plate 12 is disposed between the second housing portion 113 and the housing frame 114. That is, the housing frame 114 is disposed between the cathode plate 12 and the anode plate 13, so that there is a certain distance between the cathode plate 12 and the anode plate 13. With this arrangement, water can enter between the cathode plate 12 and the anode plate 13, thereby ensuring that both the cathode plate 12 and the anode plate 13 can contact water, so as to ensure the electrolysis effect of the hydrogen peroxide generator 10.

[0090] In some embodiments, refer to Figures 1 to 4 As shown, the first housing part 111 and the second housing part 113 are fixed together by a snap-fit ​​mechanism to form an electrolytic cavity between them. Of course, the fixing method between the first housing part 111 and the second housing part 113 can also be a threaded connection, magnetic fixation, etc. This disclosure does not limit this, as long as it can fix the first housing part 111 and the second housing part 113 together and form an electrolytic cavity between them.

[0091] In some embodiments, refer to Figure 5 As shown, in order to ensure the sealing of the electrolytic cavity formed between the first housing part 111 and the second housing part 113, a sealing ring 19 is provided at the periphery where the first housing part 111 and the second housing part 113 are connected, so as to achieve a sealed connection between the first housing part 111 and the second housing part 113 through the sealing ring 19.

[0092] For ease of installation, please refer to... Figure 5As shown, the first housing part 111 can be a housing structure with a cavity, that is, the first housing part 111 can include a bottom wall and a surrounding wall connected to the periphery of the bottom wall, and the bottom wall and the surrounding wall are collectively configured as a housing structure with one end open; correspondingly, the second housing part 113 can be a cover structure, that is, the second housing part 113 is a cover structure arranged at the open end of the first housing part 111, and the surrounding wall of the first housing part 111 and the periphery of the first housing part 111 are provided with buckle fitting structures that are buckled to each other to realize the fixed connection between the first housing part 111 and the second housing part 113. Of course, the first housing part 111 and the second housing part 113 can also be housing structures with cavities, and the cavities of the first housing part 111 and the second housing part 113 are opposite to the openings of the cavities of the first housing part 111 and the second housing part 113, and collectively configured as an electrolysis cavity for containing liquid.

[0093] In some embodiments, referring to Figure 5 As shown, the liquid inlet 17 and the liquid outlet 18 are arranged on the middle frame 114 of the housing, and the liquid inlet 17 is connected with a liquid inlet pipe, and the liquid outlet 18 is connected with a liquid outlet pipe. Specifically, the liquid inlet pipe can be connected with a water supply component to transport water required for electrolysis to the housing 11 through the water supply component, and the liquid outlet pipe can be connected with a required position of a cavity of a household appliance and the like, and transport the hydrogen peroxide solution generated by electrolysis to the required position of the cavity of the household appliance and the like. In some embodiments, one of the first housing part 111 and the second housing part 113 is provided with a first avoiding hole for the liquid inlet pipe to extend out, and one of the first housing part 111 and the second housing part 113 is provided with a second avoiding hole for the liquid outlet pipe to extend out, so that the liquid inlet pipe and the liquid outlet pipe can extend out of the electrolysis cavity of the hydrogen peroxide generator 10 to communicate with external components.

[0094] In specific implementation, the liquid inlet 17 and the liquid outlet 18 can be arranged on two opposite side walls of the middle frame 114 of the housing. In some embodiments, the liquid inlet 17 and the liquid outlet 18 can be arranged at the diagonal positions of the two opposite side walls of the middle frame 114 of the housing to ensure that there is enough distance between the liquid inlet 17 and the liquid outlet 18, so that the water entering from the liquid inlet 17 can be fully electrolyzed in the electrolysis cavity and then discharged through the liquid outlet 18. Of course, the liquid inlet 17 and the liquid outlet 18 can also be arranged on the same side wall of the middle frame 114 of the housing as needed. The liquid inlet 17 and the liquid outlet 18 can also be arranged on the first housing part 111 or the second housing part 113 as needed, as long as the water supply in the electrolysis cavity and the discharge of the hydrogen peroxide solution generated in the electrolysis cavity can be realized.

[0095] In some embodiments, referring to Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the first housing part 111 is provided with a hollow hole 112 which is in communication with the outside air. The hollow hole 112 is located on the side of the first housing part 111 which is away from the middle frame 114 of the shell. The side of the cathode sheet 12 which is away from the middle frame 114 of the shell is in contact with the outside air through the hollow hole 112. In this way, the one side surface of the cathode sheet 12 is in contact with the air, and the other side surface is in contact with the water in the electrolysis cavity, thereby ensuring the electrolysis effect. In some embodiments, a first sealing gasket 15 is arranged between the side of the cathode sheet 12 which is away from the middle frame 114 of the shell and the inner wall surface of the first housing part 111, and the first sealing gasket 15 is located in the peripheral region of the hollow hole 112. In this way, the outside air is separated from the electrolysis cavity to prevent the liquid in the electrolysis cavity from leaking out through the hollow hole 112 provided on the first housing part 111.

[0096] In a specific implementation, the cathode sheet 12 can adopt a flat plate structure, that is, a non-hollow or non-perforated plate structure, to separate the liquid in the electrolysis cavity from the outside air through the cathode sheet 12. Of course, in a specific implementation, the cathode sheet 12 can not be directly in contact with the outside air, in which case the hollow hole 112 can not be provided on the first housing part 111, and correspondingly, the cathode sheet 12 can adopt a mesh or porous structure.

[0097] In some embodiments, referring to Figure 5 As shown, the hydrogen peroxide generating device 10 further includes an ion exchange membrane 14 which is arranged between the cathode sheet 12 and the anode sheet 13 and separates the internal space of the shell 11 into a cathode cavity and an anode cavity, that is, the electrolysis cavity formed in the shell 11 is separated into a cathode cavity and an anode cavity by the ion exchange membrane 14. The ion exchange membrane 14 is used to accelerate the exchange rate of ions generated by electrolysis, thereby improving the electrolysis efficiency. At the same time, the ion exchange membrane 14 can separate the hydrogen peroxide generated by the cathode sheet 12 from the anode sheet 13 to prevent the hydrogen peroxide from being oxidized by the anode sheet 13, thereby affecting the electrolysis efficiency.

[0098] In some embodiments, referring to Figure 5 As shown, a second sealing gasket 16 is arranged between the peripheral region of the side surface of the ion exchange membrane 14 facing the cathode sheet 12 and the cathode sheet 12, and between the peripheral region of the side surface of the ion exchange membrane 14 facing the anode sheet 13 and the anode sheet 13. The second sealing gasket 16 improves the sealing performance of the cathode cavity and the anode cavity to ensure the electrolysis effect.

[0099] In one specific embodiment, referring to Figure 5As shown, the cathode sheet 12 and the anode sheet 13 are further provided with a middle shell frame 114. In order to ensure the sealing effect, the outer peripheral region of the anode sheet 13 and the second shell part 113, the outer peripheral region of the ion exchange membrane 14 and the middle shell frame 114, and the outer peripheral region of the cathode sheet 12 and the middle shell frame 114 can be provided with the second sealing gasket 16.

[0100] Exemplarily, referring to Figure 5 As shown, the hydrogen peroxide generating device 10 comprises a first shell part 111 and a second shell part 113 connected with each other, and an electrolysis cavity is formed between the first shell part 111 and the second shell part 113. The periphery of the first shell part 111 and the second shell part 113 is provided with a sealing ring 19. In the electrolysis cavity, the first sealing gasket 15, the cathode sheet 12, the second sealing gasket 16, the middle shell frame 114, the second sealing gasket 16, the ion exchange membrane 14, the second sealing gasket 16, the anode sheet 13 and the second sealing gasket 16 are sequentially arranged in the direction from the first shell part 111 to the second shell part 113.

[0101] In some embodiments, the first shell part 111 has a cavity with an opening facing the second shell part 113. Four corners of the cavity of the first shell part 111 are respectively provided with positioning columns extending towards the second shell part 113. The first sealing gasket 15, the cathode sheet 12, the second sealing gasket 16, the middle shell frame 114, the second sealing gasket 16, the ion exchange membrane 14, the second sealing gasket 16, the anode sheet 13 and the second sealing gasket 16 are sequentially arranged on the positioning columns.

[0102] In some embodiments, in order to realize the water supply to the cathode cavity and the anode cavity through the liquid inlet pipe, a distribution pipe communicating with the liquid inlet pipe can be arranged on the middle shell frame 114. The distribution pipe penetrates the ion exchange membrane 14, so as to supply water to the anode cavity through the distribution pipe. Correspondingly, in order to realize the liquid discharge from the cathode cavity and the anode cavity through the liquid outlet pipe, a collecting pipe communicating with the liquid outlet pipe can be arranged on the middle shell frame 114. The collecting pipe penetrates the ion exchange membrane 14, so as to collect the liquid in the anode cavity to the liquid outlet pipe through the collecting pipe.

[0103] In some embodiments, referring to Figure 5 As shown, the cathode sheet 12 is a flat plate structure, so as to isolate the outside air and the electrolysis cavity through the cathode sheet 12. Specifically, the cathode sheet 12 comprises a first metal substrate and a conductive carbon substrate layer coated on the surface of the first metal substrate. The first metal substrate can be selected from any one or a combination of at least two of a metal platinum mesh, a metal nickel mesh or a stainless steel mesh. The conductive carbon substrate layer comprises a carbon material, and the carbon material is preferably carbon black or doped carbon material.

[0104] In specific embodiments, the conductive carbon-based material can be coated on the surface of the first metal substrate and pressed to form a three-phase gas diffusion electrode. The gas diffusion electrode has efficient gas molecule transmission channels and abundant hydrogen peroxide reaction sites. Oxygen molecules in the air can pass through the electrode sheet and obtain electrons on the other side of the electrode sheet to generate hydrogen peroxide. Specifically, the cathode chemical reaction formula is: O2+2H2O+4e-→2H2O2. Thus, the cathode sheet 12 needs to contact air on one side and electrolyte on the other side.

[0105] In some embodiments, referring to Figure 5 , the anode sheet 13 is a flat plate structure, a mesh structure, or a porous structure. Specifically, the anode sheet 13 includes a second metal substrate and a transition metal coating layer coated on the surface of the second metal substrate and having catalytic activity. The material of the second metal substrate includes any one or a combination of at least two of titanium, nickel, or platinum, and the composition of the transition metal coating layer is selected from any one or a combination of at least two of ruthenium, iridium, tantalum, palladium, or oxides thereof. For example, referring to Figure 13 to 19 , the anode sheet 13 is a porous structure, in which the shape of the pores can be any shape such as a circle, a square, or an irregular shape, and the number can be specifically set according to actual needs, which is not limited in the present disclosure. Specifically, the thickness of the anode sheet 13 is not less than 0.5 mm. The anode chemical reaction formula is: 4OH-→O2+2H2O+4e-.

[0106] It can be understood that when the anode sheet 13 is a flat plate structure, the electrolysis cavity is a hollow structure formed between the cathode sheet 12 and the anode sheet 13, and when the anode sheet 13 is a mesh structure or a porous structure, the electrolysis cavity is a hollow structure formed between the cathode sheet 12 and the second housing portion 113. Water can flow in the electrolysis cavity through the anode sheet 13, thereby ensuring that the shape of the anode sheet 13 can be specifically set according to actual needs.

[0107] It should be noted that in specific embodiments, the anode sheet 13 and the cathode sheet 12 need to be connected to a direct current power supply, which is external to the housing 11 of the hydrogen peroxide generator 10, to provide electrons for the anode sheet 13 and the cathode sheet 12 by the direct current power supply, and the current is controlled at 0-10 A.

[0108] In other embodiments, referring to Figures 1 to 5As shown, the shell 11 comprises a first shell part 111 and a second shell part 113 connected to each other, and an electrolysis cavity is formed between the first shell part 111 and the second shell part 113. In the electrolysis cavity, a first cathode sheet 121, an anode sheet 13 and a second cathode sheet 122 are sequentially and spacedly arranged in a direction from the first shell part 111 to the second shell part 113, and the liquid inlet 17 and the liquid outlet 18 are both in communication with the electrolysis cavity. In this way, the first cathode sheet 121 and the anode sheet 13 are spaced apart by a certain distance, and the second cathode sheet 122 and the anode sheet 13 are spaced apart by a certain distance, so that the first cathode sheet 121, the second cathode sheet 122 and the anode sheet 13 can all contact the water entering the electrolysis cavity, thereby ensuring the electrolysis effect of the hydrogen peroxide generating device 10. In addition, by arranging two cathode sheets and one anode sheet, compared with arranging one cathode sheet and one anode sheet, the electrolysis efficiency of the hydrogen peroxide generating device 10 can be better ensured.

[0109] It should be noted that the number of cathode sheets and anode sheets arranged in the shell 11 is not limited to one, and two, three or more can be arranged as needed. For example, in the embodiment as shown in Figures 13 to 19 , the shell 11 of the hydrogen peroxide generating device 10 is provided with one cathode sheet 12 and one anode sheet 13; in the embodiment as shown in Figure 14 , the shell 11 of the hydrogen peroxide generating device 10 is provided with two cathode sheets and one anode sheet 13, and the two cathode sheets are respectively a first cathode sheet 121 and a second cathode sheet 122.

[0110] In some embodiments, referring to Figure 15 , Figure 16 , Figure 19 and Figure 13 , the first shell part 111 is provided with a first hollow hole 1111 in communication with the outside air, the side of the first cathode sheet 121 away from the anode sheet 13 contacts the outside air through the first hollow hole 1111, and a first sealing gasket 191 is arranged between the side of the first cathode sheet 121 away from the anode sheet 13 and the inner wall surface of the first shell part 111, and the first sealing gasket 191 is located in the peripheral region of the first hollow hole 1111. In this way, one side surface of the first cathode sheet 121 can contact the air, and the other side surface can contact the water in the electrolysis cavity, thereby ensuring the electrolysis effect; and by arranging the first sealing gasket 191, the outside air and the electrolysis cavity are separated, preventing the liquid in the electrolysis cavity from leaking out through the first hollow hole 1111 arranged on the first shell part 111.

[0111] In some embodiments, referring to Figure 16 , Figure 19 and Figure 16As shown, the second shell part 113 is provided with a second hollow hole 1131 in communication with the outside air, the side of the second cathode sheet 122 away from the anode sheet 13 is in contact with the outside air through the second hollow hole 1131, and the second sealing gasket 192 is arranged between the side of the second cathode sheet 122 away from the anode sheet 13 and the inner wall surface of the second shell part 113, and the second sealing gasket 192 is located in the peripheral region of the second hollow hole 1131. In this way, the side surface of the second cathode sheet 122 can be in contact with the air, and the other side surface can be in contact with the water in the electrolysis cavity, so as to ensure the electrolysis effect; and the second sealing gasket 192 is arranged to separate the outside air from the electrolysis cavity, so as to prevent the liquid in the electrolysis cavity from leaking out through the second hollow hole 1131 arranged on the second shell part 113.

[0112] In some embodiments, referring to Figure 19 and Figure 19 As shown, the first cathode sheet 121 and the anode sheet 13 are provided with a first partition 193 to separate the first cathode sheet 121 and the anode sheet 13 through the first partition 193, and the second cathode sheet 122 and the anode sheet 13 are provided with a second partition 194 to separate the second cathode sheet 122 and the anode sheet 13 through the second partition 194. In this way, the first cathode sheet 121, the second cathode sheet 122 and the anode sheet 13 can all be in contact with the water entering the electrolysis cavity, so as to ensure the electrolysis effect of the hydrogen peroxide generating device 10.

[0113] Specifically, referring to Figure 16 As shown, the first partition 193 can include two first partition strips, both of which are located between the first cathode sheet 121 and the anode sheet 13 and are oppositely arranged at the edge portions of the first cathode sheet 121 and the anode sheet 13; and the second partition 194 can include two second partition strips, both of which are located between the second cathode sheet 122 and the anode sheet 13 and are oppositely arranged at the edge portions of the second cathode sheet 122 and the anode sheet 13. Of course, the first partition 193 and the second partition 194 can also be square box structures, as long as they can separate the cathode sheet and the anode sheet 13.

[0114] In some embodiments, referring to Figure 19 and Figure 16As shown, the first shell part 111 is formed with a receiving groove 1112 with an opening facing the second shell part 113, the first cathode sheet 121, the anode sheet 13 and the second cathode sheet 122 are sequentially arranged in the receiving groove 1112, and the second shell part 113 is arranged at the opening of the receiving groove 1112 to form an electrolysis cavity; the first shell part 111 is provided with a mounting groove 1113 surrounding the receiving groove 1112, the mounting groove 1113 is provided with a third sealing gasket 195, and the side of the second shell part 113 facing the first shell part 111 is in abutting cooperation with the third sealing gasket 195. In this way, the first cathode sheet 121, the anode sheet 13 and the second cathode sheet 122 can be conveniently installed in the electrolysis cavity, and the sealing of the electrolysis cavity is ensured.

[0115] Specifically, in order to ensure the reliability of the sealing, referring to Figures 13 to 15 As shown, a protruding column corresponding to the mounting groove 1113 can be arranged on the side of the second shell part 113 facing the first shell part 111, and when the second shell part 113 is mounted on the first shell part 111, the protruding column exerts a pressing force on the third sealing gasket 195 in the mounting groove 1113, thereby ensuring the firmness of the sealing between the first shell part 111 and the second shell part 113.

[0116] In some embodiments, referring to Figure 17 , Figure 18 and Figure 17 As shown, the first shell part 111 has two opposite side walls, and the liquid inlet 17 and the liquid outlet 18 are arranged on the two opposite side walls of the first shell part 111, respectively. In this way, the liquid inlet 17 and the liquid outlet 18 are arranged to have sufficient distance therebetween, so that the water entering from the liquid inlet 17 can be fully electrolyzed in the electrolysis cavity and then discharged through the liquid outlet 18. Of course, the liquid inlet 17 and the liquid outlet 18 can also be arranged on the same side wall of the first shell part 111 according to the needs, as long as the water can be supplied to the electrolysis cavity and the hydrogen peroxide solution generated in the electrolysis cavity can be discharged.

[0117] In some embodiments, referring to Figure 18 and Figure 19As shown, the height position of the outlet 18 is higher than the height position of the inlet 17 in the height direction of the first shell part 111 towards the second shell part 113, i.e. the up-down direction in the drawing. That is, the inlet 17 is arranged at a relatively low position, and the outlet 18 is arranged at a relatively high position, which not only facilitates the water to enter the electrolysis cavity through the inlet 17 smoothly, but also avoids the water in the electrolysis cavity from being discharged through the outlet 18 quickly, i.e. ensures that the water in the electrolysis cavity can stay in the electrolysis cavity for a relatively long time, and ensures that the water can fully contact the first cathode sheet 121 and the second cathode sheet 122 to ensure the electrolysis effect. Of course, the relative height of the inlet 17 and the outlet 18 is not limited to the above definition, and can be reasonably arranged according to actual needs.

[0118] In some embodiments, referring to Figure 13 As shown, the first shell part 111 and the second shell part 113 further form an inlet cavity 1114 and an outlet cavity 1115, which are respectively located on both sides of the electrolysis cavity. The inlet 17 communicates with the electrolysis cavity through the inlet cavity 1114, and the electrolysis cavity communicates with the outlet 18 through the outlet cavity 1115. That is, the water first enters the inlet cavity 1114 through the inlet 17, and then enters the electrolysis cavity through the inlet cavity 1114. By arranging the inlet cavity 1114, a certain amount of water can be stored to ensure the efficiency of water supply to the electrolysis cavity. The hydrogen peroxide solution generated by electrolysis in the electrolysis cavity first enters the outlet cavity 1115, and then is discharged through the outlet 18.

[0119] In some embodiments, referring to Figure 19 and Figures 13 to 16 As shown, the first cathode sheet 121, the anode sheet 13 and the second cathode sheet 122 are all provided with an electrically connected sheet 131, and the shell is provided with a mounting port, and the mounting port is provided with a sealing cover 196, and the sealing cover 196 is provided with a mounting socket for the electrically connected sheet 131 to pass through. It should be understood that the first cathode sheet 121, the second cathode sheet 122 and the anode sheet 13 all need to be connected to a direct current power supply, and the direct current power supply is externally arranged outside the shell of the hydrogen peroxide generator 10. Through the above arrangement, the first cathode sheet 121, the second cathode sheet 122 and the anode sheet 13 are connected to the external power supply, so as to provide electronic supply for the first cathode sheet 121, the second cathode sheet 122 and the anode sheet 13 by the direct current power supply. Specifically, the current can be controlled at 0-10A.

[0120] In specific implementation, an installation gap can be formed on the side wall of the first shell part 111 and passing through the slot opening of the accommodating slot 1112. After the second shell part 113 is covered on the first shell part 111, the installation gap is covered, so that the first shell part 111 and the second shell part 113 jointly form the installation opening. In specific installation, the sealing cover 196 can be installed at the installation gap, and then the second shell part 113 is covered on the first shell part 111.

[0121] In some embodiments, as shown in Figure 19 , Figure 13 , the periphery of the first shell part 111 is provided with a first mounting part, the periphery of the second shell part 113 is provided with a second mounting part corresponding to the first mounting part, and the first shell part 111 and the second shell part 113 are fixedly connected through the fastener 197 penetrating the first mounting part and the second mounting part. Specifically, the first mounting part and the second mounting part can both be screw columns, and the fastener 197 can be a screw, so as to realize the installation and fixation between the first shell part 111 and the second shell part 113 through the screw, which is simple in structure and convenient to assemble.

[0122] In some embodiments, as shown in Figure 14 , Figure 19 , Figure 6 , at least one of the first shell part 111 and the second shell part 113 is provided with a third mounting part 1116 on the side facing away from the other, so as to fix the hydrogen peroxide generating device 10 on the electrical appliance through the fastener penetrating the third mounting part 1116.

[0123] Specifically, the third mounting part 1116 can be arranged on only one of the first shell part 111 and the second shell part 113, or the third mounting part 1116 can be arranged on both of them respectively, so as to ensure the reliability of the fixation between the hydrogen peroxide generating device 10 and the electrical appliance.

[0124] It should be noted that the fixation between the first shell part 111 and the second shell part 113 is not limited to screw connection, but can also be achieved by buckling or the like; and the fixation between the hydrogen peroxide generating device 10 and the electrical appliance is not limited to screw connection, but can also be achieved by buckling or the like.

[0125] Some other embodiments of the present disclosure provide a laundry washing apparatus 20, which comprises a laundry treatment cavity 21, a water inlet waterway 22 and a hydrogen peroxide generating device 10. The water inlet waterway 22 is arranged in communication with the laundry treatment cavity 21, and washing water can be supplied into the laundry treatment cavity 21 through the water inlet waterway 22. The hydrogen peroxide generating device 10 is arranged on the water inlet waterway 22 or in the laundry treatment cavity 21, and is used to electrolyze water to generate hydrogen peroxide solution, so as to supply the hydrogen peroxide solution into the laundry treatment cavity 21.

[0126] Specifically, when the hydrogen peroxide generating device 10 is arranged on the water inlet channel 22, the hydrogen peroxide generating device 10 can directly utilize the water in the water inlet channel 22 to realize electrolysis, and deliver the hydrogen peroxide solution generated by electrolysis to the clothes treatment cavity 21 through the water inlet channel 22, without additional multiple addition of detergents to improve the cleaning capacity of the clothes washing equipment 20; when the hydrogen peroxide generating device 10 is arranged in the clothes treatment cavity 21, the hydrogen peroxide generating device 10 can directly utilize the water in the clothes treatment cavity 21 to realize electrolysis, and generate hydrogen peroxide solution to wash clothes. Specifically, the clothes washing equipment 20 can be a drum washing machine, as shown in Figure 7 ; the clothes washing equipment 20 can also be a pulsator washing machine, as shown in Figures 20 to 25 ; of course, the clothes washing equipment 20 can also be other equipment for washing clothes, which is not limited in the present disclosure.

[0127] It should be noted that the clothes treatment cavity refers to a cavity for treating clothes. In a washing machine, for example, a drum washing machine, the clothes treatment barrel, the door body and the door seal ring enclose a space to form a clothes treatment cavity; in a clothes dryer, the drum assembly of the clothes dryer forms a clothes treatment cavity.

[0128] In some embodiments, the hydrogen peroxide generating device 10 includes a shell 11, an inlet 17 and an outlet 18 arranged on the shell 11, and a cathode sheet 12 and an anode sheet 13 arranged in the shell 11 for electrolyzing water to generate hydrogen peroxide solution. When the hydrogen peroxide generating device 10 is arranged on the water inlet channel 22, the inlet 17 is in communication with the inlet of the water inlet channel 22, and the outlet 18 is in communication with the outlet of the water inlet channel 22; alternatively, the inlet 17 is in communication with the water inlet channel 22, and the outlet 18 is in communication with the clothes treatment cavity 21; in this way, the cleaning capacity of the clothes washing equipment 20 can be improved without additional multiple addition of detergents. Specifically, the water inlet channel 22 can include a first water inlet pipe section and a second water inlet pipe section, and the hydrogen peroxide generating device 10 is connected between the first water inlet pipe section and the second water inlet pipe section. Of course, the water inlet channel 22 can also include only one section of water inlet channel, and the hydrogen peroxide generating device 10 is connected at the inlet or outlet of the water inlet channel 22.

[0129] In some embodiments, as shown in Figures 20 to 22 , the water inlet channel 22 includes a first water inlet branch 221 and a second water inlet branch 222, both of which are in communication with the clothes treatment cavity 21, and the hydrogen peroxide generating device 10 is arranged on one of the first water inlet branch 221 and the second water inlet branch 222. That is, the clothes washing equipment 20 has at least two water inlet branches for supplying water into the clothes treatment cavity 21, and the hydrogen peroxide generating device 10 is arranged on one of the water inlet branches.

[0130] In this way, when the function of the hydrogen peroxide generating device 10 needs to be used, the water supply branch provided with the hydrogen peroxide generating device 10 can be controlled to supply water into the clothes treatment cavity 21, so that the water supplied by the water supply branch is electrolyzed by the hydrogen peroxide generating device 10 to generate hydrogen peroxide solution, and the generated hydrogen peroxide solution enters the clothes treatment cavity 21 to clean, deodorize, disinfect, sterilize, and the like of the clothes in the clothes treatment cavity 21. When the function of the hydrogen peroxide generating device 10 does not need to be used, the water supply branch not provided with the hydrogen peroxide generating device 10 can be controlled to supply water into the clothes treatment cavity 21, that is, the original water supply mode of the clothes washing equipment is adopted to supply water into the clothes treatment cavity 21, so that the original washing function of the clothes washing equipment is maintained, that is, the implementation of the original function of the clothes washing equipment is not affected. Of course, it is also feasible to provide only one water supply path 22 and arrange the hydrogen peroxide generating device 10 on the water supply path 22.

[0131] It should be noted that the water supply path 22 is not limited to including two water supply branches, and three water supply branches or more water supply branches can be provided according to needs, and the hydrogen peroxide generating device 10 is arranged on one of the water supply branches.

[0132] For example, referring to FIG. 2, the water supply path 22 includes three water supply branches, which are a first water supply branch 221, a second water supply branch 222, and a third water supply branch 223. The first water supply branch 221, the second water supply branch 222, and the third water supply branch 223 are all in communication with the inner cavity of the clothes treatment cavity 21, and the hydrogen peroxide generating device 10 is arranged on the second water supply branch 222. Figures 23 to 25

[0133] In some embodiments, referring to FIG. 3, the clothes washing equipment includes a dispensing assembly 23 connected between the water supply path 22 and the clothes treatment cavity 21, and the hydrogen peroxide generating device 10 is arranged outside the dispensing assembly 23 and connected with the dispensing assembly 23. Figure 20 Specifically, the dispensing assembly 23 has a detergent dispensing opening, and the dispensing assembly 23 is connected between the water supply path 22 and the clothes treatment cavity 21 to dispense detergent into the dispensing assembly 23 through the detergent dispensing opening, and to supply water into the dispensing assembly 23 through the water supply path 22 to flush the detergent in the dispensing assembly 23, so as to realize dispensing of the detergent in the dispensing assembly 23 into the clothes treatment cavity 21. By arranging the hydrogen peroxide generating device 10 outside the dispensing assembly 23 and connecting the hydrogen peroxide generating device 10 with the dispensing assembly 23, compared with installing the hydrogen peroxide generating device 10 in the clothes treatment cavity 21, on the one hand, the installation and fixation of the hydrogen peroxide generating device 10 are more convenient, and on the other hand, the hydrogen peroxide generating device 10 is facilitated to be connected to the water supply path 22.

[0134] ​​

[0135] Taking a drum washing machine as an example, a drum washing machine typically includes a cabinet and a drum assembly 24 disposed inside the cabinet. The drum assembly 24 may specifically include an outer drum and an inner drum disposed inside the outer drum. The dispensing component 23 may be disposed in the area between the cabinet and the drum assembly 24, specifically in the area between the cabinet and the outer drum. The hydrogen peroxide generator 10 is disposed outside the dispensing component 23 and connected to the dispensing component 23.

[0136] Of course, it is also feasible to install the hydrogen peroxide generator 10 in other locations within the laundry equipment. For example, the hydrogen peroxide generator 10 can be placed in any suitable installation area between the cabinet and the outer drum, such as by directly fixing the hydrogen peroxide generator 10 to the cabinet, or by placing the hydrogen peroxide generator 10 side by side with the dispensing component 23, etc.

[0137] In some embodiments, refer to Figure 21 , Figure 22 and Figures 1 to 5 As shown, the hydrogen peroxide generator 10 includes a housing and an inlet 17 and an outlet 18 disposed on the housing. The housing 11 is provided with a cathode plate and an anode plate for electrolyzing water to generate hydrogen peroxide solution. The inlet 17 of the hydrogen peroxide generator 10 is connected to the water inlet channel 22, and the outlet 18 of the hydrogen peroxide generator 10 is connected to the dispensing component 23.

[0138] With this configuration, water is supplied to the hydrogen peroxide generator 10 through the water inlet channel 22. The hydrogen peroxide solution generated by the electrolysis of water in the hydrogen peroxide generator 10 is introduced into the dispensing component 23, and then enters the inner cavity of the clothes processing chamber 21 through the dispensing component 23. This realizes the use of the flow channel of the dispensing component 23 to transport the hydrogen peroxide solution into the inner cavity of the clothes processing chamber 21. With this configuration, there is no need to set an additional inlet for the hydrogen peroxide solution to enter the clothes processing chamber 21, which requires little modification to the original clothes washing equipment, is easy to process and manufacture, and has low cost.

[0139] Of course, if manufacturing costs and other factors are not considered, it is also feasible to additionally provide an inlet for introducing hydrogen peroxide solution on the garment processing chamber 21, directly connect the inlet 17 of the hydrogen peroxide generator 10 to the water supply line, and connect the outlet 18 of the hydrogen peroxide generator 10 to this inlet through a connecting pipe. In other words, the hydrogen peroxide solution generated by the hydrogen peroxide generator 10 is not limited to entering the garment processing chamber 21 through the dispensing component 23, but can also directly enter the garment processing chamber 21 through the connecting pipe.

[0140] It should be noted that the number of cathode and anode plates disposed within the housing 11 is not limited to one. For example, in... Figures 13 to 19In the shown embodiment, the housing 11 of the hydrogen peroxide generating device 10 is provided with one cathode sheet 12 and one anode sheet 13; in the shown embodiment, the housing 11 of the hydrogen peroxide generating device 10 is provided with two cathode sheets and one anode sheet 13, the two cathode sheets being a first cathode sheet 121 and a second cathode sheet 122. Figure 20 In the shown embodiment, the housing 11 of the hydrogen peroxide generating device 10 is provided with two cathode sheets and one anode sheet 13, the two cathode sheets being a first cathode sheet 121 and a second cathode sheet 122.

[0141] In some embodiments, referring to Figure 21 and Figures 20 to 22 As shown, the dispensing assembly 23 comprises a dispensing housing 230, a first water inlet passage 232, a second water inlet passage and a water outlet passage 231, the first water inlet passage 232, the second water inlet passage and the water outlet passage 231 all communicating with the inner cavity of the dispensing housing 230, the dispensing housing 230 is provided with a detergent dispensing opening, and the water outlet passage 231 communicates with the laundry treatment cavity 21.
